Must be missing something as this seems pretty obvious. All three dead ball fouls happen before the penalty for any of them is completed and there is at least one PF/USC for each team, so the penalties all offset. Disqualify A95 and B91 for fighting.
As all fouls are dead ball fouls the ball belongs to team B as team A did not make the line to gain. 1st and 10 for team B at A-50. Clock on the snap, play clock at 25. No ZAP-10 as the clock was stopped for a first down for team B.
